Abstract
In the combustion of hydrocarbon fuel there was needing to lower the volume of unburned gases and pollutant emissions and increase combustion efficiency. The first to be oxidized are the hydrogen atoms when hydrocarbon fuel is combusted and in normal conditions some of the carbon will be only partially oxidized; this is responsible for the incomplete combustion. A magnetic field unit was manufactured for altering H atom in the hydrocarbon fuel from the stable state (parahydrogen) to the more reactive unstable state (orthohydrogen) so that transform the hydrocarbon molecule from its para state to the higher energized ortho state. In this research the pollutant emissions and combustion efficiency was studied for diesel fuel in an electrical generator (100KVA) for four weeks period with and without magnetic field unit.A Flue gas analyzer unit (IMR 1400) was used for testing and analyze the exhaust of the electrical generator.The output data for magnetized diesel fuel was compared with the output data of normal diesel fuel and showed significant decreasing in pollutant emissions and increasing of combustion efficiency using the magnetic field Unit.
